The interaction of genetic and environmental contributions to immunological traits and their association with atopic disease remain unclear. Flow cytometry and in vitro cytokine responses were used to characterize immune profiles from 93 school-aged twin pairs. Using an established twin pair analytical strategy, the genetic and environmental influences on immunological traits were evaluated, along with their association with atopy. Our findings suggest strong genetic influence on several traits, particularly B cell abundance. In contrast, cytokine responses from in vitro stimulations appeared mainly shaped by environmental exposures.
Type 1 interferons (T1IFNs) are typically expressed in low concentrations under homeostatic conditions, but upon pathogenic insult or perturbation of the pathway, these critical immune signaling molecules can become either protectors from or drivers of pathology. While essential for initiating antiviral defense and modulating inflammation, dysregulation of T1IFN signaling can contribute to immunopathology, making it and its associated pathways prime targets for immune evasion and disruption by pathogens.
Acute rheumatic fever is a preventable condition that can lead to chronic illness and early death. Standard prevention with 4-weekly intramuscular (IM) benzathine penicillin G (BPG) injections for ≥10 years may be associated with poor adherence. High-dose 10-weekly subcutaneous penicillin injections (SCIP) may improve adherence by reducing injection frequency.
Allergic sensitization and reduced ability to respond to viral infections may contribute to virus-induced wheeze and asthma development in young children. Plasmacytoid dendritic cells (pDC) are rare immune cells that produce type I interferons (IFN-I) and play a key role in orchestrating immune responses against viruses.
Sepsis is a significant cause of mortality for children in Australia, particularly affecting young children, those with pre-existing health conditions and Aboriginal and Torres Strait Islander populations. The transition from hospital to home can be challenging for survivors, often leaving long-term impacts unaddressed.
Rates of several vaccine preventable diseases, and associated hospitalisation, are higher among Aboriginal and/or Torres Strait Islander children than non-Indigenous children. Western Australia has among the lowest childhood vaccine coverage in Australia, particularly among Aboriginal and/or Torres Strait Islander children. Delayed vaccination is also more common in this population. This project aimed to understand the barriers and facilitators to vaccine uptake and timeliness among Aboriginal and/or Torres Strait Islander children aged under five years in Boorloo (Perth).
A retrospective study will review episodes of anaphylaxis during bee venom immunotherapy in children, any modifications made to the dosing schedule, and the subsequent outcomes over a nine-year period in Western Australia.
Antimicrobial stewardship (AMS) is crucial for optimizing antimicrobial use and restraining emergence of antimicrobial resistance. The overall increase in reported antibiotic allergies in children can pose a significant barrier to AMS, but its impact on clinical AMS care in children has not been addressed.
In an era of expanding indications for iatrogenic immunosuppression, invasive fungal disease (IFD) remains a significant challenge in immunocompromised children, with case fatality rates ranging from 10 to 70%. Understanding of current recommendations and recent evidence is essential to guide optimal IFD management.
Dietary intake during the first year of life is a key determinant of a child's growth and development. ORIGINS is a longitudinal birth cohort study investigating factors that contribute to a 'healthy start to life' and the prevention of non-communicable diseases.
